A series of 40% Ni/CexCr1-xO2 catalysts with x = 0, 0.1, 0.3, 0.5, 0.9 and 1 were synthesized using one-pot hydrolysis method as catalysts for the methanation process. The reaction was carried out in a packed-bed and micro-channel reactors. 40 wt% Ni/Ce0.5Cr0.5O2 showed the best catalytic performance towards the methanation process at 270 °C, giving 92.63% of CO2 conversion and 90.53% of CH4 yield. The catalyst exhibited great stability after 50 h of time-on-stream with carbon deposition around 0.0056 mg h−1 was observed. The micro-channel reactor showed better performance than the packed-bed reactor in term of methane production rate which offered amount of methane production rate 109.1 mL min−1 gcat−1 which nearly 8 times greater than that packed-bed reactor.
